New, pre-packaged.

The four-channel Audison SR 4.500 amplifier with crossover is characterized by high power enclosed in ultra-compact dimensions (130 W x 4 at 4Ω).

As for the electronic design, the Audison SR 4.500 has been carefully designed for every aesthetic and functional detail, which has allowed the creation of a compact amplifier made of extruded aluminum with rounded corners, which facilitates installation in tight spaces.

Thanks to the large heat sinks on the two shorter sides of the amplifier, there is no need for internal cooling fans, which often cause noise and dust accumulation. According to tradition, SR amplifiers confirm their comprehensive vocation, equipping all models with a complete filter section, suitable for any audio system configuration.

Control elements, protected by a satin aluminum panel, are located on the upper panel of the amplifier, so they are easily accessible from the top, even after installing the device. For a system with a Audison bit processor, the filter section can be completely disabled.

You buy in a reputable Car Audio store from an authorized dealer of the Audison brand in Poland, original products with a Polish guarantee.
